Remove the Xtensa architecture

As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.

-# When building a target filesystem, it is desirable to not have to
-# become root and then run 'mknod' a thousand times.  Using a device 
-# table you can create device nodes and directories "on the fly".
-#
-# This is a sample device table file for use with genext2fs.  You can
-# do all sorts of interesting things with a device table file.  For
-# example, if you want to adjust the permissions on a particular file
-# you can just add an entry like:
-#   /sbin/foobar        f       2755    0       0       -       -       -       -       -
-# and (assuming the file /sbin/foobar exists) it will be made setuid
-# root (regardless of what its permissions are on the host filesystem.
-# Furthermore, you can use a single table entry to create a many device
-# minors.  For example, if I wanted to create /dev/hda and /dev/hda[0-15]
-# I could just use the following two table entries:
-#   /dev/hda    b       640     0       0       3       0       0       0       -
-#   /dev/hda    b       640     0       0       3       1       1       1       15
-# 
-# Device table entries take the form of:
-# <name>    <type>      <mode>  <uid>   <gid>   <major> <minor> <start> <inc>   <count>
-# where name is the file name,  type can be one of: 
-#       f       A regular file
-#       d       Directory
-#       c       Character special device file
-#       b       Block special device file
-#       p       Fifo (named pipe)
-# uid is the user id for the target file, gid is the group id for the
-# target file.  The rest of the entries (major, minor, etc) apply only 
-# to device special files.
